The following article illustrates various cases of radio signal propagation. It helps you understand why moving your indoor antenna only a few centimeters could drastically improve reception. This analysis is from 2005, however radio propagation rarely follows trends - instead it dully stays the same every year.

While it may sound like utter nonsense at first, on second thought maybe it really is: cron.standard: please provide configuration facility to avoid given filesystems Someone should really be thinking more about a serious reminder system. I've put together an iotop oneliner that logs disk actions with timestamps which pointed me to anacron. Daily mlocate updating was easy to reproduce and fine tune: simply add your HDD mount points to tho PRUNEPATHS variable of /etc/updatedb.conf . On the other hand, it took a few more attempts and many days in total to track down what causes the HDDs to still start up. When trying to further examine the issue by hand, /etc/cron.daily/standard didn't start them up on first look, perhaps because of caching. However, today after randomly testing things again, it finally did, which took me to adding CHECK_LOSTFOUND=no to /etc/default/cron . It's a pity though, that I'll have to use an alarm clock from now on.

Some years ago, I've found a few bad sectors on my WD10EARS Caviar Green drive not too long after purchasing, but I decided to simply partition around it. Actually, I can't remember now when that was, but I've either used up a major part of the disk and had nowhere to back up everything by then, or I've deliberately planned to extend the warranty by a replacement... The original purchase came standard with 3 years of warranty. The drive didn't store too precious data in general, but no attention was given to the issue for years. The fault seemed to propagate by a few dozen bad sectors over the allocated 1GB margin, injecting a few macroblock errors to 5 of my unimportant home recordings. Actually this spreading was really slow, as occasional slowdowns were indeed experienced when randomly accessing some of the files in the past, but the fix was never a priority. For serious use, I'd like to point out the importance of data scrubbing for protecting against b...

How come so few donate their free resources to volunteer computing projects ? Depending on the exact computer configuration, the difference in system power consumption between using and near-idling the CPU (~35W-80W) or GPU (~30W-100W) can be reasonably small . The difference is usually smaller than the difference between a power efficient (25-60W) and a basic system (100-200W). Hence in my view, it usually worths it to put your free resources to use in some way if your daily work does not strain your machine continuously at 100%. There's an a project of special interest that has similar aim to what I have invented earlier: It is special in that any participant can freely use the communal grid for their own purposes . Prioritization is fair - it is based on previous record of contribution. This type of project is also useful for the selfish kind, as if you think it over, you can eventually get back the contributed CPU time and energy, but at a much faster pace. It would stil...
